Where does it crash? In g_type_check_instance() for the thread with the main?

The GObject gdb plugin seems to be buggy, because it's the "saved" signal that is sent, not "changed". And the "saved" signal had an error parameter before, that has been removed. So the problem comes maybe from a plugin which was not updated.

Do you still have the core? What does gdb print? In which thread does it crash?

Normally all official gedit plugins should work fine, including those in gedit-plugins.

Is it 100% reproducible? Does it also happen with all plugins disabled?

It's maybe a plugin not updated wrt the GeditDocument::saved signal.

yes. this is 100% reproducible. problem in gedit-code-assistance plugin.

gedit-code-assistance needs a new release, I think the problem is fixed in git master.
